I’d like to see you hand draw full feature length films without ever recycling frames.

… my question is who in the hell had the time to look for 12 frames that are recycled like that.

You don’t need lots of time to do this. All of these images involve movies during a certain period in Disney’s history, specifically the point at which they had no money and so they recycled animation to safe cash. You can’t spit without hitting recycled animation in Robin Hood. Hell, at least two of its characters are straight-up traced from the Jungle Book. Find a frame of Little John and it’s bound to have been Balloo at some point.
